NOTES
: (1) The four wood screws provided should be replaced with the appropriate fasteners for stucco, brick, concrete, or
other types of siding.
(2) For buildings with vinyl siding, a vinyl siding standoff (950), should be installed between the vent cap and the
exterior wall FIG-12. Attach the vinyl siding standoff to the horizontal termination. The vinyl siding standoff prevents
excessive heat from possibly melting the vinyl siding material. Note that the horizontal vent termination bolts onto the
flat portion of the vinyl siding standoff. (shaded area in FIG-12), so that an air space will exist between the wall and
the vent termination.
NOTES:
(1) The horizontal run of vent pipe must be level and should have a ¼ inch rise for every one foot of run towards
the termination. Never allow the vent to run downward. This could cause high temperature and may present the
possibility of a fire
(2) The location of the horizontal vent termination on the exterior wall must not be easily blocked or obstructed.
Termination clearances are as follows:
(3) When installing a vent pipe in chase the minimum clearance to combustibles is 4” inches (100 mm).
